Configuration space
The OXCB950 is a single function device, with one PCI
configuration space
(and for the default cardbus mode, one
cardbus information structure).
All the required fields in the predefined PCI header region
have been implemented. This includes those fields in the
cardbus PC Card Standard that are termed
“allocated”
and
“reserved”
for cardbus applications.
This implementation is
a specific requirement for cardbus support in Windows 9x.
6.2.1
Cardbus / PCI Configuration Space Register map
The device dependant region of the PCI configuration
space contains the cardbus/pci Power Management
Extended Capability register set and
(for the cardbus mode
only
) the Tuples making up the Cardbus Information
Structure.
The format of the PCI configuration space, for cardbus and
pci modes, is as shown in the Table below.
In general, writes to any registers that are not implemented
are ignored, and all reads fromunimplemented registers
return 0.
